Isochronic Tones

Isochronic tones work by emitting sound at regular intervals: the intensity of the sound goes almost directly from 0 to 100 and back again in an evenly-spaced manner. Widely regarded as the most effective tone-based method, isochronic beats produce very strong cortical responses in the brain.

     From the creator of myNoise, Brainaural is a parametric isochronic tone generator that gives you complete control over frequencies, up to the higher Gamma waves.

Brain Waves (brainwaves) Entrainment

Brainwaves are electrical activity patterns caused by the neurons of the brain communicating with each other. Brainwaves can be detected using sensitive medical equipment such as an EEG. They provide an indication of the mental state of an individual.

Brainwaves are divided into four main categories: the Delta waves, when deep sleep occurs; the Theta waves, associated with a state of somnolence and reduced consciousness; the Alpha waves, when we are in a state of physical and mental relaxation; and the Beta waves, emitted when we are consciously alert, or when we feel agitated or tense.

Brainwave frequencies are in the range of 0.1 to 4 (Delta), 4 to 7 (Theta), 7 to 13 (Alpha) and 13 to 30 (Beta) cycles per second (Hz).

Brainwave entrainement (or synchronization), aims to cause our brainwave frequencies to fall into step with a periodic stimulus having a frequency corresponding to the intended brain-state. This can be used, for example, to induce sleep. This page uses isochronic tones as auditory stimuli.

  Wow! Thanks for this, it's really helping me to focus :-) Love that I can adjust the settings too! Fantastic.

  This is excellent for helping me do my homework!

  I combine this with the 3-Carrier binaural beats and set both on low. Super relaxing while I'm trying to chill.

  Toying with my own brain is a good way to get into reading and writing for me. Currently, I am listening to induce fear into myself, so that I might know how it feels to be the protagonist in the horror story. That, and I love being scared.

  I'm currently using this in my elementary school (5th grade) classroom for the first time. I've known about Isochronic Tones for quite some time, years really, but I've never used it in the classroom before. The change was instantaneous and dramatic.

  I usually have a lot of trouble concentrating while studying. I tend to daydream a lot and my mind starts wandering off. Then I discovered and then the isochronic tones. I must say, it has helped me heaps! Thank you Stephane!

  I'm not sure how it works, but every time I turn it on, my mind calms down almost instantly, like something of a pacifier, works better than music even. Thanks.

  This is freaking crazy. I was having a lot of trouble focusing on my assignments but now I feel super focused- kind of weird though, my head around the ear area is literally pulsing? Feels super weird (but kind of satisfying at the same time). I combined this with 'White Rain Noise' and had a great ol' time. Thank you myNoise!

  I was recently introduced to the concept of isochronic tones, but most of the online examples I found actually made me feel tense rather than relaxed. When I found the Isochronic Tones Custom Brainwave Entrainement Machine on, I was immediately hooked! I love that I can control the relative decibels of each tone, and I listen every day to help me focus and relax while I write.

  I am struggling with a boring task for work at the moment and this setting is helping me so much! I feel like I'm truly awake now, active for the first time in days. Happily bobbing my head in tune with this beat and typing away. You made my day!

  With just the Isochronic Tones playing I enter a Zen-like state. However I use this Isochronic Tones generator in combination with the Drum pattern sequencer and Gregorian Male chanting... all playing at once. Nothing can interrupt me!

  This player DEFINITELY helps me with studying and doing work. I'd recommend this to anyone who is struggling to stay focused, or anyone who just wants to stay more focused than they already are.

  I am a programmer. I need immense focus, but I used to get distracted every 5 to 10 mins. After using this tool, I can write code for hours with extreme focus. It is truly amazing!!

  The most relaxing thing ever produced. It helps me sleep, helps me lucid dream, it's just fantastic. Thanks a lot!

  I tried this particular mix of high alpha + beta waves because I wanted a focused but creative state but found myself pleasantly surprised that it almost sounds like artificial cicadas or crickets. I don't understand brainwave entrainment enough to know if or how it works, but I like messing with these generators for the fun and interesting sounds they produce. I'm never bored on this website.

  I'm a fan :) Helps me focus and concentrate. Great to study to.

  One of the best auto/free player I found for producing these tones. Really helpful. Suggested it to lot of friends who are unable to sleep or focus while studying. Kudos to developer.

  This noise lets me focus and relax at the same time; really great!

  I suffer from severe anxiety and I found that this helps calm my mind and bring me inner peace.

  By feeling this rhythm, it seems to lower my exaggerated enthusiasm. I just feel good.

  This sort of reminds me of when my cat purrs on my lap. It's comforting, if I really look for the sounds. It's best for me when I sleep.

  My muse when writing. Thank you so much for this site!

  This was an amazing help, I wrote 2 stories in 1 hour while listening to this, which, was a lot of writing (in fact each was about 1,000 words!) Thank you for helping me get out of my writer's block! ~A Grateful Customer

  Oddly enough, I use this more for distracting myself than I do for focusing. I often panic and find myself unable to sleep because all I can focus on is what is worrying me. The low beat is easy to keep my mind on.

  I have ADHD and this tone is the best tool I found to help me work on my thesis. The regular low vibration has really helped me focus and sit still for longer stretches of time. It almost feels like it's a hypnotic tone that syncs your heart with your brain in a way that eliminates external 'noise' and draws you in whichever activity you're engaged in. Wonderful series! Thank you!

  This help we stay focus during long working session. Also work well with coffee :)

  Makes someone sleepy fast!

  I feel more aware of my surroundings and more focused.

  Nearly gave myself a headache; heartbeat was becoming much more noticeable too. Still, I think this is an interesting thing to mess around with.

  The settings I'm using are making me feel terrified! I have this odd sense of dread.

  I was feeling kind of lonely, stressed and a little sad, but now I don't really... anything anymore.

  Help falling to sleep and helps having a good sleep even over a short period of time.

  If you feel powerless, activate this and hear some other music and after a bit you should feel very hyperactive!

  This is terrible! I have been listening to this for over a month now and I still don't have super strength! What is this! I'm not angry... I'm just disappointed :D

  Noisy awesomeness!

  This might just be the best thing I've found in a long time.

  Lucid dream!

  I don't know, it sounded kinda cool but I don't think it made me feel that much sleepier in general. I really wanted it to work, though.

  It acts as a multi-layered iso tones. I had never seen a generator like these before. I will test it for a while!

  What a chaser! Awesome vibes from this thing. Listened to it overnight and woke up feeling euphoria.

  I'm in the second half of my first year as a new teacher. I used this site several times during my exams and I don't know if it was helpful or not (I usually do pretty well), but even if it didn't help me concentrate directly, indirectly, it gave me a placebo effect in that I tended to concentrate more on a specific task.

  At some point it changed in my mind into a trans techno beat, which I guess is quite reasonable. Makes me feel attentive and relaxed.

  Now I take 20mg Adderall XR for ADHD (without hyperactivity, thankfully) and 10mg Lexapro for depression... Because I take both at the same time, I get a feeling of relaxation while being alert, focused, and generally inspired. I wasn't paying attention and didn't have a refill at the pharmacy in time to seamlessly move through the week. This setup really helped me out.

  So I set this up to focus... and now I'm tearing up. Whenever I hear this my eyes water.

  Gets a while to adjust and to focus on the task before one's eyes, so there's a need to be patient. The focus mode won't just magically start. But once it does, it's really something! It's almost 3am and even though I feel my body fatigue, my brain stays conscious and attentive. Truly an amazing tool for studying, big thumb up.

  Honestly saying, I didn't really witnessed any change in myself, even after hearing the tones. I guess it very depends on every person, and doesn't work that well for me. Have a good day! :)

  This is perfect for sleep, or just tranceing out and relaxing.

  I do school on an online public school called k-12, which you may have heard of before. I'm normally extremely slow in just about every topic in school. However (even though I am judging this off of the change that I just recently experienced in my most recent science class that I completed), when I tried isochronic tones while I was doing my most recent lesson, I witnessed a dramatic change.

  When I listen to this at night it helps me get to sleep, and I even need less sleep! Strangely, I feel like I didn't sleep deeply enough, but otherwise it's sure as heck an improvement on my normal sleep patterns.

  Brown, Red, Orange and Purple is a nightmare in a beautiful way.

  Putting only the red slider up with headphones on is like something from pure nightmares... And it's so cool.

  Put on headphones when you listen to this. It seems to spin around your head, and it's sooo weird, but I love it! XD

  Has helped me sleep deeply better than I have in years, I highly recommend listening before going to sleep and during sleep!

  Donated. Thank you for your work! Helps me feel better. Struggling with low levels of neurotransmitters.

  Outstanding! Really works and I love it!

  This is a very thought-invoking tone, and listening with earphones is definitely recommended.

  Wierd, but fun. Recommended.

  I don't do any kind of drugs, so instead I play around with the brainwave sounds to stimulate my brain. It really works, and I don't have to take anything harmful for it.

  I donated monies... So far I've only donated to charities where people were guilt tripping me into it on the street. When I grow up to be a rich space pirate, I will donate a galleon filled with rubies, diamonds and doubloons!

  Playing Destiny with music & this. #wrecked

  This is so good!

  I have been blending solfeggio frequencies (trialling different frequencies for different contexts - primarily how I'm feeling and what I'm doing). Finding they work best when laid under music or alternatively if I want a really deep focus, I've been using the rain noise generator, temple bells, tibetan bells, and most recently with the isochronic generator as well. Transformative app, thank you!

  Space cats purring.

  This,combined with a custom 10 hz isochronic tone from Gnaural, makes me feel physically and mentally relaxed, yet alert and agitated.

  Trying this out as a background noise to help me stay concentrated. Tiny bit of Beta, some Theta, heavy on Alpha, and a touch of Delta.

  Wow, love this. The high beta scared the crap out of me though.

  Felt strangely comfortable, like waking up in the morning after sleeping late.

  Made me feel like a zombie.

  The closest thing to Adderall I could find... This is the one!!

  This setting really gets me/ I follow the tones through my mind... left right left right. Really awesome, mentally energizing.

  This way no one can hear my thoughts.

  This sound makes your ears pop a little, so weird yet so fun. And if you want max focus, use the Alphas at medium sound and use a little delta, then combine that with grey noise... You may not consciously hear it but the sound is going and adjusts your brain... so weird yet so freaking awesome!

  Wanna be alert and calm at the same time? Try this blend of Theta and Alpha waves, with a touch of Beta wave.

  This setting is great for focusing with mild relaxation, while at work or at home ;)

  I'm using this setting for work right now. Some low, some mid and just a little high. Keeping me relaxed and focused at the same time .. Relaxed .. Focused .. Relaxed .. Focused .. I have Explosions In The Sky's music (ambient music) playing in the background at the same time. Nice!

  Actually made me a little scared.

  I love this setting! It takes away any tension/stress. I have with low delta waves, some theta and beta waves, and lots of alpha waves. This helps me keep focused while doing studying or schoolwork. Thank you for helping me! :)

  I don't normally like listening to Isochronic/Binaural beats because they make my brain feel frazzled. I came here to play around and found that this delta-heavy mix is really helping me focus. I will start listening to "deep sleep" patterns to see if they work for me. Thanks a ton!

  I wasn't planing on sharing, but just so you know, this setting here made me paranoid, starting to see things (if y'all into that). I'm going to try something smoother then. What I like about this site is that I can specifically go for what I want, and if I want I can just run or something in the background. Cheers!

  This shuts my brain down enough to enable me to get stuff done - up to and including lengthy e-mail writing sessions; something I'm 100% terrified of - and therefore helps me avoid a lot of needless panicking. I really cannot express how very grateful I am.

  This is the "Brain Balancer". Some high frequencies, some low. Keeps your brain in its ready and working state...

  I was so sleepy I started floating

  So glad I found your site! Because this technology is new to me and I'm just learning what it is and how to best adapt it for me, I love being able to "play" with the settings and find what works for me as well as having the guidance of the presets. Just listening to a combo of a preset with a personalized adjustment and J.S. Bach violin concerto in the foreground... thank you!

  This noise is great, it's super calming and none of the sounds are too high. Kept me focused while doing all my spring break homework at the last minute!

  ← TrinityPulse - mix with your favorite mynoise for additional clairvoyance and mental synergy.

  DeltaSync - less air pressure from the bass mixed into a relaxing musical pulse.

  I used to be bad at CurveFever, but then I started listening to this while playing. It increased my focus, and now I'm good instead of bad.

  I'ts very calming. I was VERY tense earlier for reasons I'd best not go into, and I listened to this and was immediatley calm.

  Nice sleepscape.

  calming; alert, has a nice beat, yet booming.

  I was in a middle of a panic attack when I came across this on tumblr, it calmed me down so fast and it works so well. I adore this whole website so much, thank you for making it!

  You would think this sound would get annoying after a few minutes. But I've been listening to this for a few hours straight as I've been working on my 3D arts homework. No issues.

  This noise allows me to relax and focus on my tasks. I'm thankful I found this amazing site. This sound goes amazing when played with Singing Bowls at all sliders equal.

  I couldn't decide between alert and concentrate and eventually made this. It got me through my final paper that I couldn't focus on to save my life! Played it quietly on headphones while in a coffeeshop setting-absolutely perfect!

  I had to write a college essay I was dreading for weeks. I'd been working on it for short periods of time, but could never focus for very long. Upon discovering this website, I decided to try it out. Skeptical at first,I found it annoying. I turned on and some music. Not only did it keep me focused, but my settings happened to mesh right in with Toto's 'Hold the line'. Thanks!

  This is an interesting noise! It's a catchy rhythm to me, and makes me want to write music based on this rhythm.

  Lovely for paper writing. Really keeps you going through that after midnight push to the finish line.

  I'm an adult writer with ADHD. This setting is not very pleasant, but if I turn it on quietly behind other generators it disappears from my notice soon. I take medication for my condition, and it helps a great deal. This sound, however, seems to boost those effects further. I can focus more effectively.

  Just perfect for focus and concentration while working on written projects ! Combined with Himalayan bowls and/or Didgeridrone and my mind escapes.

  I find that the relaxed selection/frequency, is not relaxing at all. It sounds rather high pitched, making me more alert. Maybe my brain waves are a bit "off"! The drowsy option was much more along the lines of what I consider to be relaxing. Awesome concept, site and sounds!

  Helps me think! Think it might be a tool in my getting better from burnout <3

  Love this website! I've discovered it yesterday, yet I have already downloaded the app, and am listening to relaxing or brainwave sounds, AMAZING!!

  Helps me relax, but doesn't make me fall asleep.

  Puts the Fear of God into anyone who listens to this for a long period of time. This is basically cardio-day for lazy people since your heartbeat speeds up a lot.

  Odd but interesting. Calming yet alert and attentive.

  I found this setting after messing around with it a bit and I think it sounds mystical as well as relaxing.

  This makes me feel like a high tech computer is scanning my brain and this makes me much more alert.

  Had my first midterm in 4 years, and was so worried about retaining information since it has been so long since studying. Used the learning feature of this website and got a 94% on the test. I love it.

  I attribute this to finally being able to complete a programming project I've been working on for weeks!

  Perfect for when you're tired, but want to think about something. Keeps me relaxed and somewhat focused on my thoughts as well.

  I did not customize noise and it was still pleasant.

  The fantasy setting makes me want to dance! These things really seem to work!

  As with other noises on here, deeper, lower sounds help me focus and ease tension, so I prefer the lower settings on this slider. After a while, I don't notice it's playing-- it's just soothing and great for focusing. I pair it with the bumpy tracks railroad sounds.

  It makes me sleepy.

  Relaxing. Perfect for nights when you just can't sleep.

  Nice. Helps tinitis very well.

  This is really the most helpful aid to study I have ever found. I have been taking exams for the past week, and this has helped me to focus and memorize better than anything else I have ever tried.

  So focused I did telekinesis.

  This really makes me feel alert and inspired! Working on projects has never been easier.

  This noise really helps me by making me feel neutral. It's not calming, or rousing, it just makes me feel like... me.

  Fabulous for writing NaNoWriMo.

  I find this combination great when I'm working on homework, so that I can get done without getting distracted.

  Really good for working on math homework. Helps me concentrate.

  For lucid dreaming. Good with the water stream noise.

  This really helps me when im bored! It makes my brain spark with ideas and adventures.

  As an artist, I find that some days my brain isn't in the "right mode" to draw. Using this tone generator to induce beta waves was exactly what I needed. You might have just saved a deadline or 10!

  I made my noise calming but energetic. Perfect for a hype before my job as a public speaker.

  This helped me get rid of 2 week writer's block and finish a 5 page paper without getting distracted. I also did not feel stressed when writing or anxious to finish.

  It felt like a whole -brain cleanse- many thanks!

  This really helps me focus when I write.

  It helped get rid of my migraine after a long day of school.

  After A hard day at school with lots of homework, this noise helped out a lot.

  So freaking relaxing and you just want to sleep and it sounds SO good.

  I took out most of the high pitched sounds that were rather annoying... I have no knowledge only instinct.

  Utterly entrancing in the best of ways.

  Helps so much with anxiety or just stress in general. Love it.

  This was so relaxing.

  Strong Focus

  This is amazing. And very helpful if you're stumped with writing. Truly incredible stuff.

  Calm, with some inspired focus.

  Great for sleeping.

Each slider controls a particular frequency. Adjust sliders to induce a particular mental state. Mixing adjacent sliders works best.


Our brainwave generator specifically outputs frequencies that replicate the cycles of brain waves. By syncing up your brain with these frequencies, your state of consciousness will be altered.

Because of the strong and repetitive pulsating rhythms, people who are prone to seizures or epilepsy should not use our brainwave generator. Children and pregnant women should also use caution when considering using brainwave entrainment.
